IEHP Geospatial Analysis Tip Sheet
1 - Searching the Map
Selecting the magnifying glass icon will open search bar that will function just like Google maps.
Example 1 - Victorville, CA
Example 2 - Hemet, CA
2 - Toggling Map Layers
With the Layer Control menu you can turn on & off certain layers of the map to customize the viewing experience. In this example we toggle the Zip Code layer.
3 - Zoom Controls
Selecting the \(+\) sign will zoom the map in to see a narrower view
Selecting the \(-\) sign will zoom the map out to see a wider view
Alternatively you can use your mouse scroll wheel to achieve the same results.
4 - Resetting the Map View
After altering the map view in any way to quickly reset the map select the push pin icon.
5 - Interaction Tools
Zoom In Selection Tool
To get a close up view into a specific area the Zoom In Selection Tool is a great utility.
Hit the Z key to swap to the Zoom In Selection tool
Panning Tool
With the Panning Tool we can freely move the map around to view different areas of the map.
Hit the F key to swap to the Panning tool
Rectangular Selection
The rectangular selection tool allows us to select large areas very quickly.
Hit the A key to swap to the Rectangular Selection tool
Radial Selection
The Radial Selection tool allows us create a circular selection region, this is great for determining how far patients live from a specific clinic.
Hit the S key to swap to the Radial Selection tool
In this example lets see how many patients live within a \(10\) mile radius of our Barstow clinic
Lasso Selection
In instances where the rectangular or radial selection is not precise enough consider using the Lasso selection tool to draw a custom region.
Hit the D key to swap to the Lasso Selection tool.
